A furnace that stands off for long stretches gets away with a weak igniter or a sluggish inducer motor. Homes in Vermont run heat about nine months a year, from September through May. That kind of schedule works against a system with anything wrong with it, because the burner and heat exchanger are cycling on and off through the cold months rather than sitting idle waiting to be tested by one hard week. A part that is going bad tends to show it early here, while the ignition system is still being asked to prove itself night after night.
Before a new furnace or heat pump gets specified, a contractor has to open up what is already feeding air and power through the house. The ducts might be sized for a smaller unit than what is being installed. The electrical panel might not have room for a new circuit without upgrading it first. Half the homes in Vermont were built in 1976 or earlier (2020-2024 ACS 5-year). That figure is why so much of the work is inspection before it is installation. A contractor measures duct runs, checks panel capacity, and looks at how the existing system was tied in before writing up what the new one needs. None of that gets skipped because a house looks fine from the basement stairs.
Does where you live in Vermont strain your HVAC system more?

A county with a heavier storm record means the outdoor unit is more likely to take a direct hit from wind, hail or ice at some point in its life. That risk affects how it should be mounted and anchored, not just where it sits. Have a contractor check the pad or bracket underneath it, how firmly it is secured, and the cabinet itself for dents or loose panels.
Vermont has no state license for HVAC contractors.
